We look at the division of 165336 by 81 
Our goal is to divide 165336 by 81.

On to step 1:
The number 81 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 81

Advancing to step 2:
81 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 81

Let's proceed to step 3:
If we divide 165 by 81, we get 2 and a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 162 from 165 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 81

Going ahead to step 4:
The number 81 fits into 33 0 times, leaving a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 33, we end up with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 81

Step 5:
When dividing 333 by 81, we get 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
Subtracting 324 from 333 leaves us with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 81

Step 6:
The number 81 fits into 96 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 2041.0
If we take 81 away from 96, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
81 can be fit into 150 1 times, resulting in a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 2041.1
Subtract 81 from 150 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 8:
The number 81 fits into 690 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 2041.18
If we subtract 648 from 690, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
81 goes into 420 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 2041.185
Subtracting 405 from 420 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
If we divide 150 by 81, we get 1 and a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 2041.1851
Subtracting 81 from 150 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 11:
When dividing 690 by 81, we get 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 2041.18518
If we subtract 648 from 690, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
420 divided by 81 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 2041.185185
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
When dividing 150 by 81, we get 1 with a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 2041.1851851
Deduct 81 from 150 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 14:
81 can be fit into 690 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 2041.18518518
If we subtract 648 from 690, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 2041.18518518, with a leftover of 4.2e-08.
